Hi Guys,
I need some help here.

I want to interlink the Combo Box with the Check Box.
I'm using this formula on the Combo Box { If('SMM-CHKBOX'.Value=false,"","TICK-Mark") }.
This is running smoothly.

But when I select from the Combo Box, Check Box doesn't change it's value.

When I use this formula on Check Box,
{ If(SMM_ComboBOX.Value="TICK-Mark",true,false) }

This is the error that I receive.
"This rule creates a circular reference between properties, which is not allowed."

Hi @AlexRavens ,

That is correct - dependency can only be in one direction otherwise you get the circular reference you have received.

I am assuming on the setting in the Combo Box is the DefaultSelectedItems, so I suggest you do the following (I cannot test this presently and there may be a reset required in there as well)

On the CheckBox, put OnSelect

UpdateContext({varSMM: Self.Value})

and the Default

varSMM

On the ComboBox OnChange

UpdateContext({varSMM: Self.Selected.Value = "TICK-MARK"})

DefaultSelectedItems

{ Value: If( varSMM, "TICK-MARK", Blank() ) }

I am also assuming the output of the Combo Box is .Value
